scsi/scsi_bus: fix races in REPORT LUNS
Currently scsi_target_emulate_report_luns iterates over the child device list twice, and there is no guarantee that this list is the same in both iterations. The reason for iterating twice is that the first iteration calculates how much memory to allocate. However if we use a dynamic array we can avoid iterating twice, and therefore we avoid this race.
